Remarkably fast diesels | Six of the Best

It is more expensive than ever to refuel from the black pump - so it better be worth it, right?


Porsche Panamera 4S, 2017, 89k, £32,990

You don’t have to go back very far in the car industry annals to find a time when the idea of a fast diesel would be risible. Oil burners were once the preserve of sooty black cabs and tired old bin lorries; the idea of them wafting you to 60mph in a pleasing head rush was about as realistic as using a large spring to put mankind in orbit. But then, with what seemed like precious little buildup, a perfect storm of wider economic concerns, legislation and technical developments made diesel engines not just very good, but good enough even for the likes of Porsche and Bentley. So good in fact, that if we were choosing a used Panamera to crush continents in today, the V8-powered 4S is genuinely the car we’d buy. Gravelly thrust at its finest - and available here and now for a smidge over £30k.

Alpina D5, 2012, 71k, PH Auction

One rung below the Porsche - or possibly equivalent to it if you prefer six cylinders to eight - is pretty much any big oil burner that Alpina ever breathed on. Buchloe recognised early on that the torque-happy performance a modern diesel engine provides was the perfect foil for its comfort-focused approach to chassis tuning, and the combination produced a rash of long-distance heroes. Accordingly, you can’t really miss with a D5, which in F10 format gets 352hp and 516lb ft of torque from a modified N57. Less than the mighty Porsche, perhaps, yet sufficient for a sustained 171mph on the right road. This one looks in great nick and is due to go under the PH hammer this coming Tuesday.

Range Rover TDV8, 2012, 37k, £34,995

While a used Range Rover should absolutely be on your fast diesel shortlist, we’d actually intended to draw your attention to the L405, based on its superior handling. But this one-owner, late-model L322 was too good to ignore. Yes, they’ve enjoyed a Clarkson Farm-based price bump, and few people would describe the ownership experience as faultless - but a 4.4-litre Vogue with just 37k on the clock is old-school (albeit BMW-owned) Land Rover at its finest. Granted, in another life the same V8 was a Ford truck engine, but you won’t think about that much while driving. You’ll be too busy dreamily staring out of the window and absorbing admiring glances from posh girls on horseback. A charming British rose among German thorns, in other words.

Audi S6 Avant, 2022, 28k, £47,985

Of course, if you’d rather proceed somewhere quickly incognito, you can hardly go wrong with an upmarket Audi - especially those with an S badge on the boot lid. The last S6 seemed like a throwback when it launched with a diesel V6 (and in many ways it was), but that just means you get all the things that make a speedy oil burning wagon good to own: usability, practicality, economy and 0-62mph in five seconds-ish. This one is barely run-in on that scale, though its freshness means you’ll still need to part with the best part of £50k to put it on the driveway. Obviously there are more exciting ways to spend that cash - but we’re not talking about heartstrings here. Quite the opposite.

Mercedes E 450d, 2024, 14k, £62,500

If you’re adamant it must be something from the current crop of cars that still fit the bill, you can hardly do better than the latest E 450d. Mercedes track record on diesel cars is no less storied than its German rivals, and the W214, as well as being very pleasant to drive, adds mild hybridisation to the attribute list. Also, courtesy of its 3.0-litre straight six, you get 372hp and 553lb ft of torque - the latter sufficient to rival the current E53. Matt Bird called it Mercedes at its most persuasive when we drove one back in 2024. Expect the same, but for around £20k less than it cost when new. Bargain.

Maserati Quattroporte, 2017, 28k, £23,000

Well, we say ‘bargain’ - if you really don’t want to pay much at all (comparatively speaking), the Maserati Quattroporte might be your best bet. True, the omnipresent VM Motori-built V6 is not going to shatter any performance records - and friends and enemies alike might point out that you missed out on one of the great V8s by choosing the diesel variant - yet the sheer left-field-ish-ness of it arguably makes it worth a second look. That and the fact it costs just £23k to bag yourself a lightly used example from 2017. Or possibly less than that if the Strait of Hormuz remains closed to shipping for much longer...

I’m slightly surprised at how expensive they all are I guess I’m getting old. Having said that, I’d take the Alpine: wafting to the Continent on that wave of torque would be joyous.

Really weird when Audi gave the S6 an oil burner. Not long ago either.

Just seems the two shouldn’t mix to me.

I’d have the Merc out of this lot.

That wood/leather colour combo on the Alpina is challenging.

No appeal with any of them for me.
If I was given one FOC they all be sold straightaway other than the Alpina.

£50k for a 4yo diesel Audi and it's not a V12.

Mental.

I have a soft spot for a large capacity dieselboxedin and have owned 2 from this list.

I'd give the Panamera a go out of these 6.....but why did the vendor take the photo's with the what I assume to be air suspension in 'off road' mode?, surely that's not its default ride heightnerd

As the spread between the cost of diesel and unleaded has never been wider, doesn t that makes a big, punchy diesel a less attractive proposition than before? The better mpg benefit is swallowed up by the higher cost of a tank.

Getting that way but the torque is nice from a big diesel

A Wonderful list. Simply being diesel is enough for me to take anyone of them.The odd ball being the Mazerati which is surely better served with the petrol V8. If I had to choose it would be the Porsche quite simply because I have never owned one and my current keeper is an individual ACs 530d.

This is missing the V8 in the older Bentayga and Audi SQ7. I have the latter, and the engine s absolutely brilliant. That said, the car weighs as much as a Chieftain tank, so is only about as fast as Golf R, despite 440bhp and nearly 700lb feet of torque. But it's faster (and cheaper, I believe) than the Range Rover in the list.

ETA, not cheaper, for comparable mileage, it turns out.

I have toyed with the idea of a petrol V6 Audi S5 (b9) but whilst the mpg looks ok on paper a 25mpg average is the norm. Meanwhile, with my current 2015 A5 3.0TDi quattro, I get that decent torque when needed and usually average 45mpg, which is bang on the claimed combined mileage.

I am wondering this. My car does about 34-38mpg in the real world. A modern petrol unit in an SUV is probably more efficient?

The Range for me, but that price needs quite some adjustment. I paid 10k for my one owner L322 2010, with 49,000 miles, 1 owner, full dealer history, matching tyres and a higher spec.

That Range Rover asking price is absurd. £35k for a 14 year old diesel RR?

Agree, especially the Quattroporte. Still, it looks the part though I guess!

Whenever I read these used selection articles I always find the cars are more expensive than I would have thought, and that isn't any different here!

(And wot, no Skoda Favia VRS? laugh )
